It's probably worth noting that a given cosmology may not use the standard clumps of matter orbiting other clumps of matter model. Mine assumes a Material Plane with a rotating spherical body at its center.
Other models are equally valid, say, a disc borne on the back of a giant turtle. D&D's Great Wheel has many different models of plane as well: Acheron's cubes, Bitopia's twin layers, Baator's nine stacked layers, et al.
Really nit-picky arguments aside, I rather like the proposed changes to Rope Trick and plan to use them in my campaign. It will curb abuses and allows for much easier countering than the SRD version.
BTW, what exactly does STAP refer to?
